NOTE DISK OR SHEET.

SPECIFICATION forming part of Letters Patent No. 547,838, dated October15, 1895.

Application filed October 23, 1894. Serial No. 526,674. (No model.)

T 0 all whom it may concern.-

Be it known thatI, GUSTAV A. BRACHHAU- SEN, a subject of the Emperor ofGermany, residing at Jersey City, Hudson county, State of New Jersey,have invented a new and Improved Note Disk or Sheet, of which thefollowing'is such a full, clear, and exact description as will enablethose skilled in the art to which the invention appertains to make anduse the same.

My invention relates to that character of musical instruments wherein anote disk, sheet, or barrel is employed to operate the vibrating tonguesor other music-producing devices; and said invention consists in theform of teeth to be employed on the note disk, sheet, or barrel.

The object of the invention is to produce strong and reliable teeth,wherein each tooth consists of a single piece provided with a supportopposite to the working face thereof and on each side of the tooth forat least a portion of its length, and to this end I construct teeth inthe manner hereinafter described and illustrated in the accompanyingdrawings, wherein Y Figure 1 is a top view of a note-disk provided withteeth made in accordance with my invention. Figs. 2, 3, and 4. are likeviews of different forms of teeth made in accordance with my invention,and Fig. 5 is a side view of the form of tooth represented in Fig. 3.

In the drawings, A represents the body portion of a note-disk, which ispreferably made of metal, it being understood, however, that anysuitable material may be employed and that my invention is equallyapplicable to a note sheet, cylinder, or other equivalent thereof.Projecting from the body A of the disk or its equivalent are note-teetha, each of which consists of a single piece cut from the body at theworking face of the tooth, as indicated at so, and struck up into curvedform in the direction of its width and so as to form a support I) forthe tooth opposite to the working face 0 thereof and on each side of thetooth for at least a portion of its length, as indicated at (Z. In Fig.2 aform of tooth is shown wherein the side supports 01,, extend for onlya portion of its length, it being cut away from the body of the disk, asshown at e, and hasa flat portion thereof forming the working face 0.Figs. 3 and 5 illustrate anote-tooth wherein the support d on one sideextends throughout its length and the support 61 on the other sidethereof extends for only a portion of its length, leaving a severedportion 6, as indicated. In Fig. at the tooth is represented as severedalong both sides at substantially right angles to the working facethereof, as indicated at 6, thereby leaving the support cl extendingonly a portion of the length of the tooth on each side thereof.

It will be observed that by my invention each tooth is severed from themetal or body portion of the disk only at or near the highest part ofthe tooth or the working face thereof, whereby the necessary height ofthe tooth can be obtained and at the same time the greatest amount ofrigidity provided, there being little liability of breakage ordisplacement of the parts.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. A note disk or its equivalent, each tooth of which consists of asingle piece stamped uptinto curved form in the direction of its Widthand severed from the body of the note disk at the Working face of thetooth and along the sides thereof for a portion of its length and formedintegral with such note disk at the sides for a portion of the length ofthe tooth and opposite to the working face thereof, substantially as andfor the purposes specified.

2. A note tooth of a single piece stamped up into curved form in thedirection of its width and severed from the note disk alongside theworking face of the tooth and also along the side at substantially rightangles to said working face, whereby the necessary height of the toothcan be obtained and the greatest amount of rigidity provided,substantially as described.

3. A note disk having operating teeth or projections, each formed of asingle piece stamped up into curved form in the direction of its widthand severed fromthe body of the metal on the line of the working ends oredges and along the lines of both sides, whereby the necessary height ofthe tooth can be obtained and the greatest amount of rigidity provided,substantially as and for the purposes specified.
